Convenient ultrasonic preparation of a water stable cluster-based Cadmium(II) coordination material and highly sensitive fluorescent sensing for biomarkers DPA and 5-HT

In recent years, a new type of micro-porous material, namely metal organic framework material, has received more and more attention from many basic and industrial fields because these materials possess unique advantages. In this work, through the powerful sonochemical preparation method, a three-dimensional cluster based CdII-MOFs, {[Cd(abtz)(2)(H2O)(2)]center dot(ClO4)(2)center dot H2O}(n) (1, abtz = 1-(4-aminobenzyl)-1H-1,2,4-triazole) can be quickly synthesized in the facile ultrasonic method. Powder X-ray diffraction (PXRD) measurement confirms that these bulky samples 1 (synthesized on different ultrasonic powers and ultrasonic time conditions) were pure. In addition, ultrasonic chemical time and irradiation power did not change the structure of composites materials 1. SEM and morphological changes of 1 in the ultrasonic synthesis are also determined. Moreover, 1 exhibits good stability, the structure of 1 can be maintained not just in various solvents, and in aqueous environments with pH values from 2 to 12. Photo-luminescent experiment also reveals that complex 1 has the excellent application prospect as highly sensitive sensing material for the biomarker DPA (2,6-pyridine dicarboxylic acid) and 5-HT (5-hydroxytryptamine) through the photo-luminescence turn-on and turn-off effect, respectively. Further photo-luminescent measurements also show that different ultrasonic powers and ultrasonic time can effectively induce fluorescent sensing enhancement for biomarkers DPA and 5-HT based on the water stable clustered-based cadmium(II) coordination framework.

Synthesis, physical and photo-electrochemical characterizations of a new hybrid host-guest complex [Cu-12(C2N3H2)(8)Cl][(PW12O40)]

Through careful choice of reduction conductions, a new hybrid host-guest compound [Cu-12(C2N3H2)(8)Cl][(PW12O40)] was synthesized hydrothermally in the presence of 1, 2, 4 triazole as structure-directing agent. The material has been characterized by single-crystal X-ray diffraction, chemical analysis, FT-IR spectroscopy, thermal analysis and UV-Vis diffuse reflectance. The compound based on a two-dimensional (2D) supramolecular porous coordination polymer [Cu-12 (C2N3H2)(8)Cl](3+) can accommodate in its cavities the Keggin polyoxotungstate anions, with host-guest interactions crystallizing in the monoclinic system (Space Group: C2/m). The metal organic species and Keggin anions are connected via hydrogen bonds and Cu center dot center dot center dot O short contacts giving rise to a three-dimensional architecture. The optical study shows a direct transition (1.60 eV) assigned to the O2-: 2p -> Cu+: 4 s transition. The transport properties revealed a semiconductor comportment; the thermal variation of log (conductivity) versus 1000/T was fitted by a least square method to a straight line whose slope gave an activation energy of 54 meV. The chrono-amperometry and photo-electrochemistry, carried out in Na2SO4 (0.5 M) electrolyte, indicate n-type conduction with a flat band potential of +0.10 V-SCE, making [Cu-12(C2N3H2)(8)Cl][(PW12O40)] a promising solar material.

Gestational exposure to tebuconazole affects the development of rat fetal Leydig cells

Tebuconazole is a triazole fungicide, used in agriculture to treat phytopathogenic fungi, and as a biocide, has been reported to be related to reproductive and developmental toxicity. The purpose of this study was to investigate the effect of tebuconazole exposure on rat fetal Leydig cells and fetal testis during pregnancy. Pregnant Sprague-Dawley rats were randomly divided into 4 groups, daily gavaged with corn oil (as a control), 25, 50, and 100 mg/kg body weight tebuconazole for 10 days (from the 12th day of pregnancy). Tebuconazole increased fetal serum testosterone and progesterone levels at a dose of 100 mg/kg. Exposure to 100 mg/kg tebuconazole significantly caused an increase in the number of fetal Leydig cells per testis without inducing cell aggregation. Tebuconazole up-regulated the expression of Star, Cyp11a1, Hsd17b3, and Fshr and their proteins. Further investigation found that tebuconazole caused increased phosphorylation of AKT1, ERK1/2, and mTOR, the level of BCL2, as well as the decrease of Beclinl, LC3B, and BAX, which may contribute to the fetal Leydig cell autophagy and proliferation. In conclusion, in utero exposure of tebuconazole causes the proliferation of fetal Leydig cells. (C) 2020 Elsevier Ltd. All rights reserved.

Isavuconazole Therapeutic Drug Monitoring during Long-Term Treatment for Chronic Pulmonary Aspergillosis

Isavuconazole is the newest triazole antifungal, and it displays a favorable pharmacokinetic and safety profile. Less is known about its long-term use in immunocompetent hosts. We performed a retrospective service evaluation of isavuconazole therapeutic drug monitoring in patients with chronic pulmonary aspergillosis. Adverse events (AEs) and dose adjustments made during routine clinical practice were recorded, and AEs were classified based on Common Terminology Criteria for Adverse Events v5.0. Forty-five patients (mean age, 64 years) had 285 isavuconazole blood drug levels measured (mean level, 4.1 mg/liter). A total of 117 measurements (41%) were performed on patients on a 100-mg daily dose instead of 200 mg, and all had blood levels of >1 mg/liter. Age (P = 0.012) and a daily dose of 200 mg versus 100 mg (P = 0.02) were independent predictors of levels of >6 mg/liter. AEs were recorded for 25 patients (56%). The mean drug level at the first measurement was 5.5 +/- 2 mg/liter for patients reporting AEs, compared with 4.2 +/- 1.7 mg/liter for those not reporting AEs (P = 0.032). The cutoff threshold best predictive of an AE was 4.6 mg/liter (area under the concentration-time curve, 0.710). Sixteen patients (36%) discontinued isavuconazole therapy due to AEs. Twenty-six patients (58%) continued on isavuconazole beyond 6 months. Asthma (P = 0.022) and a daily dose of 200 mg versus 100 mg (P = 0.048) were associated with AEs of grade 2 or higher. A reduced daily dose (100 mg versus 200 mg) of isavuconazole resulted in satisfactory drug levels in a substantial number of patients; it was better tolerated and enabled continuation of therapy for prolonged periods.

1,2,3-Triazoles as leaving groups in SN(A)r-Arbuzov reactions: synthesis of C6-phosphonated purine derivatives

A new method for C-N bond transformations into C-P bonds was developed using 1,2,3-triazoles as leaving groups in SNAr-Arbuzov reactions. A series of C6-phosphonated 2-triazolylpurine derivatives was synthesized for the first time, with the isolated yields reaching up to 82% in the C-P-bond-forming event. The SNAr-Arbuzov reaction of 2,6-bistriazolylpurines follows the general regioselectivity pattern of the C6-position being more reactive towards substitution, which was unambiguously proved by X-ray analysis of diethyl (9-heptyl-2-(4-phenyl-1H-1,2,3-triazol-1-yl)-9H-purin-6-yl)phosphonate.

Synthesis of co-crystals of anti-cancer nandrolone as a potential leads towards treatment of cancer

Co-crystals are emerging as members of supramolecular family having particular practical and fundamental significance for chemists, crystallographers, pharmaceutical scientists, and theoreticians. The presented study is focused to synthesize anti-cancer co-crystals of commercially available nandrolone (1), a synthetic anabolic-androgenic steroidal drug. Co-crystallization is done using economical and green grinding and reflux methods to obtain nandrolone (Nan): salicylic acid (Sal) and nandrolone (Nan): 3-amino-1,2,4-triazole (Triz) co-crystals, in 2:1 and 1:1 stoichiometric ratios, respectively. The structural analysis and characterization were carried out using single-crystal X-ray diffraction, and vibrational spectroscopy. Nandrolone (1) crystallizes in monoclinic P2(1) space group, while the co-crystal-I (Nan:Sal) and co-crystal-II (Nan:Triz), co-crystallized in the orthorhombic P2(1)2(1)2(1) space group. The intermolecular hydrogen bonds O-H center dot center dot center dot O, C-H center dot center dot center dot O, N-H center dot center dot center dot O, O-H center dot center dot center dot N, and N-H center dot center dot center dot N between the active pharmaceutical ingredient (nandrolone) and co-formers (salicylic acid, and 3-amino-1,2,4-triazole) stabilize the structures of cocrystals. In vibrational spectroscopy of co-crystal-I (Nan:Sal), the blue shifts in stretching frequencies of hydroxyl group from 3417.9 cm(-1) to 3427.8 cm(-1) further supported the hydrogen bond interactions between API and co-former. Similarly, in co-crystal-II (Nan:Triz) the NH2 stretching frequency from 3331.4- 3413.4 cm(-1) to 3312.7 cm(-1), supported the interaction of NH2 with API via intermolecular interaction. Nandrolone (1) and both co-crystals were found to be non-cytotoxic against 3T3 normal fibroblast cell line. Nandrolone (IC50 = 1.0 0.1 mu M), co-crystal-I (Nan:Sal) (IC50 = 1.6 +/- 0.3 mu M) and-II (Nan:Triz) (IC50 = 1.8 +/- 0.1 mu M) showed anti-cancer potential against cervical cancer HeLa cell line. While doxorubicin (IC50 = 1.2 +/- 0.2 mu M) was used as standard tested compound. SYNOPSIS Two new non-cytotoxic co-crystals of synthetic anabolic-androgenic steroidal drug nandrolone (Nan) with pharmaceutically acceptable salicylic acid (Sal), and triazole (Triz) were synthesized and their structures were elucidated using single-crystal X-ray diffraction, and vibrational spectroscopy. Quantitative analysis of -OH and -NH2 intermolecular interactions between API and co-former by Hirshfeld surface analysis further supported the role of various functionalities towards the stability of co-crystals. Both co-crystals were found to be non-cytotoxic against 3T3 normal fibroblast cell line. Co-crystal-I (Nan:Sal) and co-crystal-II (Nan:Triz) were found to be selectively active against HeLa cancer cell line (IC50 = 1.6 +/- 0.3 mu M), (IC50 = 1.8 +/- 0.1 mu M). (c) 2020 Elsevier B.V.

Synthesis and energetic properties of homocubane based high energy density materials

The energetic properties of homocubane derivatives have been evaluated for the first time. The newly synthesized compounds have been fully characterized by spectroscopic methods and single crystal X-ray analysis. Detailed computational studies carried out using the B3LYP/6-311++G(d,p) level of theory reveal that these compounds have higher densities and higher heat of formation as compared to common hydrocarbon fuels. The calculated performances of these compounds in terms of their ballistic properties, particularly density specific impulse (rho I-sp), in liquid and in solid propellant systems are substantially superior to those of the conventional fuel RP1 and binder HTPB, respectively. TGA-DTG analysis confirmed that most of these compounds are thermally stable with high onset temperatures. Most of the compounds, except oxadiazole, triazole and triazine containing cages, are also kinetically stable in terms of their HOMO-LUMO energy gap. Quite remarkably, three compounds emerged as excellent candidates for volume-limited applications owing to their high density, density specific impulse as well as kinetic and thermodynamic stabilities.

Neutral Chiral Tetrakis-Iodo-Triazole Halogen-Bond Donor for Chiral Recognition and Enantioselective Catalysis

Halogen bonding represents a powerful tool in the field of noncovalent interactions. However, applications in enantioselective recognition and catalysis remain almost nonexistent, due in part to the distinct features of halogen bonds, including long covalent and noncovalent bond distances and high directionality. Herein, this work presents a novel chiral tetrakis-iodo-triazole structure as a neutral halogen bond donor for both chiral anion-recognition and enantioinduction in ion-pair organocatalysis. NMR-titration studies revealed significant differences in anion affinity between the halogen bonding receptor and its hydrogen bonding parent. Selective recognition of chiral dicarboxylates and asymmetric induction in a benchmark organocatalytic reaction were demonstrated using the halogen bond donor. Inversions in the absolute sense of chiral recognition, enantioselectivity, and chiroptical properties relative to the related hydrogen donor were observed. Computational modeling suggested that these effects were the result of distinct anion-binding modes for the halogen- versus hydrogen-bond donors.

Design, Synthesis, Evaluation and Molecular Docking Studies of Novel Triazole Linked 1,4-Dihydropyridine-isatin Scaffolds as Potent Anticancer Agents

A series of novel triazole linked isatin-dihydropyridine hybrids (N1-N15) have been synthesized and examined for their anti proliferative activity against human cancer cell lines viz. HeLa, Huh-7, PC-3, IMR-32 and MCF-7. All of the synthesized hybrids have shown moderate to potent cytotoxicity against all the tested cell lines except IMR-32. Compounds N1, N2 and N13 have displayed an enhanced inhibitory potency against Huh-7 cell line as compared to the standard drug, doxorubicin. Out of the three, N2 has shown the highest in vitro inhibitory action with IC50 values of 6.73 +/- 0.33 mu M and 17.94 +/- 0.23 mu M against Huh-7 and MCF-7 cell lines, respectively. The docking studies of these most potent compounds have also been investigated which identified that N2 might be an excellent drug-like candidate worthy of further pursuit.
